Application filed August or, 1910.

To all whom may concern:

Be it known that E, dorm J. Maserati, a citizen. of the United States, residing at Kingsviile, in the county of Nueces and State of Texas; have invented certain new and useful Improvements in Automobile l l heels, of which the following is a. specification, reference being bad therein to the accompanying drawing.

This invention relates to wheels for vehicles and the principal object. of the same is to provide a wheel that can he readily at tached to the usual'iclly andwhich is provided with means that will absorb all shocks and jars, have a firm engagement with the road to prevent skidding and which will automatically remove mud and the like therefrom.

in carrying out the objects of the inventiongencrally stated above it will be understood, of course, thatthe essential features thereof are necessarily.susceptible of changes in details and structural arrangements, one preferred and practical. embodiment of which is shown in the accompanying drawings, whcreinz Figure 1 is a view in side elevation oi" the improved wheel. Fig. 2 is an enlarged transverse sectional view taken on the line 2--2, Fig. 1. Fig. 3 is a fraguuuitary view partly in section and partly in elevation showing the manner of attaching the tire to the folly. Fig. (i is a fragmentary view in elevation of a. variation of the invention.

deferring to the accompanying drawings by numerals it will he soon that the improved wheel. comprises the usual huh 1, spokes 2 and telly 3. A tire rim at that is. preferably formed of steel is dctachabl s fastened to said telly 3 by the bolts 5 and nuts 6, hearing washers 7 being interposed between the nuts and the telly. The tire rim 4: is in the form of a circular tube the outer surface of which is provided. with regularly spaced threaded openings 8 which aline with the similarly spaced threaded sockets 9. Cylinders 10 which have enter-- nally threaded inner ends .l-l for detachable and adjustable engagement with the sockets 9. are also similarly tlnrcaded at the outer ends 12 for detachable and. adjustable engagement with the threaded o 'ici'iingrs 8. Said cylinders project well beyond the outer surface of the tire rim as shown in the drawings. The outer ends of the cylinders are provided with internal threads 13, and said cylinders are also provided with additional internal threads 11 "which extend to the rear ends thereof.

The cylinders 10 have their rear ends closed by the threaded disks 15 which adjustaloly engagc'the threads 1 Said disks are provided with a central opening 1.6 that is threaded and similar but smaller surrounding openings 17. Openings 17 are engaged by the threaded ends of plugs 18 that project into the cylinders.

The internal outer end threads of cylinders 10 are engaged by the threaded guide collars 19 that are provided with outturncd annular fiat flanges 30 that overlap the outer ends of said cylinder. The internal. threads 14 of the cylinders 10 are engaged by the threaded guide collars 2i.

Plunger cylinders 22 are slidablein cylinders 1'0 and are guided therein hy the collars 19 and 21. The inner ends of cylinders 29. are internally threaded for the reception 7 of the threaded closure disks 23. Said disks 23 are provided with a central opening 24 that aline with the central openings of disks 15, and are also provided with surrounding openings 25 that aline with the plugs 18.

The outer ends ot plungcrs 22 are internally threaded and at.- the inner ends of said threaded portions, said pl angers are sealed by the plates 26. This arrangement provides a threaded recess at the outer end of each plunger a nd. an externally threaded resilient plug 27 is rcmovably seated in each recess. The threaded central openings of disks 15 have the threaded end 28 of the piston. rods .59 engage therewith. Said rods project through the control openings 24 of the plunger disks 2 and have pistons locked to the annular ilanoics 3O thcrcoi'i by the nuts 31. Said pistons are preferably formed of the 'ilatcs 32 and ii and the interposed Flexible disk 34 the outer edge of which projects beyond the similar edges of the plates 32 and 3 Springs arc coiled about piston rods 99. said s 'iringzs being interposed between disks 15 and 2 3 and op 'iose the inward movements of the plunger-s in the form of the invention shown in Fig. 4-. the tire rim 4- bas plates 36 riveted ture is the same as that described in connection with Figs. 1, 2, and 3 of the drawings.

From ,the foregoing description it will be seen that the plungers 22 will slide in the cylinders when in contact with the road I way against the tension of springs 17 and bases for said the pressure of the air in said cylinders. When the plungers leave the roadway, the springs. 17 and the air pressure in cylinders 10 will force the plungers 22 outward to their original positions.

'The plugs carried by the plungers are pre erably of rubber and will obviously firmly engage with the roadway to prevent skidding and it will also be clear that mud or other material that willadhere to the plungers will be forced therefrom by the movements of the plungers, What I claim as my invention is 1. A wheel comprising a rim outwardly projecting cylinders detachably connected thereto, adjust-able bottoms for said cylin-.

ders, guide collars adjustably connected to said cylinders, plungers slidablein said cylinders and guided by said collars, adjustable plungers, sai'd bases provided with a central opening, piston rods detachably connected to the bottoms of said cylinders and projecting throiigh the openings in the bases of said plungers, pistons carried by the projected ortions of said rods, springs carried by said rods and interposed between the bottoms of the cylinders and the bases of the plungers, and road-gripping means carried by said plungers. 2. A wheel comprisinga rim provided with sockets, cylinders in said sockets and signature in presence projecting beyond the same, cylindrical plungers slidable in said cylinders and each providedwith a base opening, means in said cylinders for guiding said plungers piston rods adjustably mounted in said cylearned by said rods within saidplungers,

gripping means carried by said plungers.

4. A' wheel comprising a rim provided with sockets, cylinders in said soc ets, adjustable plates closing the inner ends of said cylinders, hollow plungers slidable in said cylinders, road enga 'ng means carried by 1 the outer ends of said plungers, piston rods carried by said plates an d'pro ecting into said plungers, and pistons carried by said rods and arranged in said plungers.

In testimony whereof I hereunto afiix my of two Witnesses.
